Answer 1

import psutil

process = filter(lambda p: p.name() == "YourProcess.exe", psutil.process_iter())
for i in process:
  print i.name,i.pid

Give all pids of "YourProcess.exe"

Answer 2

I don't think you will be able to find a purely python-based, portable solution without using /proc or command line utilities, at least not in python itself. Parsing os.system is not ugly - someone has to deal with the multiple platforms, be it you or someone else. Implementing it for the OS you are interested in should be fairly easy, honestly.
